Class A vs. Class B Office Pricing in Miami: Where the Gap Sits

If you've been watching the Miami office market this fall, you've probably noticed that every headline quotes a different rent number. Countywide averages, trophy-tower records, submarket medians — they're all true, and they're all measuring different things. One of the most useful splits for a small business budgeting an office search is the one between Class A and Class B space, and the Q3 2026 data just gave us the clearest picture yet of how wide that gap has grown.

The $20-per-foot divide

According to Cushman & Wakefield's Q3 2026 Miami MarketBeat, Class A office space across Miami now asks an average of $74.77 per square foot per year, up 6.1% from a year ago. Class B space averages $54.76 per square foot, up a much gentler 1.3%. That's a gap of exactly $20.01 per square foot — meaning the same 2,000-square-foot office costs roughly $40,000 more per year in a Class A building than in a comparable Class B property.

The vacancy picture splits the same way, just in reverse. Class A vacancy sits at 16.0%, while Class B is far tighter at 11.0%. Translation: the flashy new towers still have space to fill at premium prices, while the well-located, reasonably priced buildings — the kind that dominate the office rental Coral Gables market — are the ones filling up.

Overall, Miami vacancy fell to 13.9% in Q3, down a full percentage point year over year, with average asking rents rising to $67.77. Savills' Q3 count, reported by Commercial Observer, tells a similar story: countywide asking rents averaged $68.50, up 8.4% year over year, with availability tightening to 14.6%.

Where Coral Gables lands

Here's where it gets interesting for anyone comparing submarkets. Savills' data puts average asking rents in Brickell and Coconut Grove above $90 per square foot, and Cushman & Wakefield pegs the Miami CBD at $77.63. Coral Gables, by contrast, averages around $58–60 per square foot according to current Yardi Research data on CommercialCafe — roughly Class B pricing for a submarket that offers Class A quality of life: walkable streets, Miracle Mile dining, abundant parking, and a city government that actually courts business.

That value equation is not going unnoticed by big tenants. The most telling deal in Cushman & Wakefield's Q3 report wasn't in Brickell at all — it was City National Bank's 134,000-square-foot headquarters move from Downtown Miami to Coral Gables, one of the largest relocations in the county this year. When a major bank runs the same math a 5-person firm runs, and lands in the Gables, that says something about where the smart money sees value. (We covered the broader Gables momentum behind moves like this in our Q3 rent breakdown.)

Why the gap keeps growing

Two forces are at work. At the top of the market, scarcity: Savills notes only about a dozen available blocks over 50,000 square feet remain in all of Miami-Dade, and the next new towers — Santander's and Ken Griffin's Brickell projects — likely won't deliver before 2029. Trophy space can keep raising prices because tenants who need it have nowhere else to go; Google just expanded again at 1450 Brickell, and Banco Sabadell renewed nearly 50,000 square feet at 1111 Brickell.

At the middle of the market, discipline: Class B rents grew just 1.3% because that's where price-sensitive tenants — small firms, professional practices, satellite offices — actually shop. The result is a market where paying up for a building's letter grade buys prestige, but not necessarily a better daily experience for your team.

What a small business should actually pay for

If you're weighing office space Coral Gables options against a Brickell address, the honest question is what the extra $30–40 per square foot buys you. For most small businesses, the answer is: a lobby your clients see for ninety seconds. The things that affect your workday — commute, parking, lunch options, meeting space, lease flexibility — don't follow the class label. A full breakdown of the monthly math is in our cost comparison from earlier this month.

There's also a third path the class data doesn't capture: furnished executive suites. Because you're renting a ready-to-work office rather than raw square footage, you skip the build-out, the furniture, and the long-term commitment that make traditional leases risky at today's prices — while still getting a professional address in one of Miami's most prestigious submarkets.

Get Gables quality without the Brickell price tag

Gables Executive Offices puts your business steps from Miracle Mile in fully furnished executive suites Coral Gables companies have trusted for years — with staffed reception, conference rooms, and flexible terms that let you scale without betting on a five-year lease in a rising market. In a quarter where the Class A/Class B gap hit $20 a foot, a furnished office Miami businesses can move into next week is the rare option that doesn't force the trade-off.
